I do almost the same; I do not reboot to the other slice to upgrade  
it,
instead I use the current slice to upgrade, and if that fails  
reboot to
the other slice (the backup slice). It's the same idea, with one less
reboot.

This dual-boot-slice (or disk :) setup also allows for the UFS->UFS2
transition.


	This sounds nice except that I do not have my disk already  
partitioned like this.  Can I take a 4.7 machine (for example) and  
live repartition it to be like this?
